How to reset a Mac without losing data
It’s easy to reset your Mac without losing data by backing up files on your Mac in advance and restoring them after reset. To clearly illustrate the process:
Follow the guide below to reset your Mac to factory resets without losing any data now:
Part 1: Save your Mac on an external storage device
Save the Mac with Time Machine
Step 1: Connect an external storage device that can be used to your Mac.
Step 2: A window will appear asking you how to use the drive. Select ‘Use as a backup disk’. If you don’t see the window, go to the Apple System Preferences menu, then click Time Machine. Click Select a backup drive and choose your external drive. (If the external hard drive appears playback only on your Mac or if it’s not formatted as Time Machine requires, you’ll need to reformat it.)
Step 3: Then Time Machine will back up your Mac automatically. Generally speaking, the first backup will take a long time. If Time Machine is blocked for the preparation of the backup, check the correction in the linked page.
After choosing one of the above methods to back up your Mac, you can now start resetting your MacBook Pro, MacBook Air, iMac, or another Mac.
